Definitions

  • the invention relates to a fastening device for an actuating cable with an actuating jacket, which is provided at at least one end with a connecting part which is radially and axially immovably inserted into the opening of a holder, the opening being substantially U-shaped with a U-leg.
  • actuation cables are used in a large number of applications, for example for actuating hoods, throttle valves, gears or the like. They each have a flexible actuating jacket and an actuating core, which is axially slidably guided therein - usually in the form of an actuating wire designed as a rope or strand, the actuating core serving to transmit the path.
  • connection part is arranged at both ends of the actuating jacket, by means of which the actuating jacket is fixed by means of a holder on components, for example on the body of motor vehicles.
  • the actuating wire passes through the connecting parts and projects outward beyond them, and can be connected to the actuating member at one end via end pieces and to the organ to be actuated at the other end.
  • a fastening device of the type mentioned for such actuation cables can be found in EP-0 ⁇ 0 ⁇ 86 717 B1.
  • the holder for the connection part is designed as a sheet metal part which has an opening into which the connection part can be inserted axially. The edges of the opening fit into an annular groove.
  • a clip is provided for the axial securing, which is inserted into the receiving groove.
  • the opening of the holder is essentially U-shaped with U-legs. However, the end sections of the U-legs are so closely spaced that it is not possible to insert the connecting part in the radial direction.
  • the known fastening device is designed to be relatively complex and additionally requires a securing clip to secure it in the axial direction. This complicates the attachment of the connecting part considerably, in particular when the holder is located in a place that is difficult to access.
  • the invention is therefore based on the object of providing a fastening device which has a simple structure and in which the connecting part can be inserted into the holder without difficulty even in poorly accessible locations.
  • this design of the fastening device allows a radial insertion of the connecting part into the holder. After reaching the end position, snap-in elements snap into one another Secure the connector slipping out again.
  • the axial securing can - if it is only necessary in one direction - be provided by providing a stop on the connecting part. If the axial fixation is to be given in both directions, this can be achieved in a simple manner in that either the connecting part or the holder has a receiving groove into which the other part surrounds. Additional parts such as locking clips or lock nuts are then not required.
  • the connecting part has V-shaped latching webs which rest against correspondingly V-shaped end sections of the U-legs, and that the latching webs and end sections are provided with the latching elements.
  • the end sections can have locking projections behind which the locking webs grip.
  • the latching projections should preferably be further apart than the U-legs outside the end sections, so that the latching projections do not hinder the insertion of the connecting part and only the latching webs interact with the latching projections.
  • the locking webs are designed to be elastically resilient - for example by appropriate choice of material or cross-section - that when the connector is inserted into the opening, it moves over the locking projections and then springs back again.
  • the locking projections are preferably integrally formed on the connecting part, ie in one piece with them, and should consist of a plastic, in particular a sprayable plastic, with the outer jacket of the connecting part.
  • a design in which the locking webs are wider than the thickness of the holder is particularly expedient. In this way they protrude axially over the bracket. This allows them to be by hand or by means of an appropriate Tool approached each other and can thus be brought out of engagement with the locking projections. In this way, the connection part can also be removed from the holder if this is desired.
  • the actuating cable (1) shown in FIG. (1) has an actuating jacket (2) in which an actuating wire (3) is guided so as to be axially movable.
  • the actuating jacket (2) is seated in a metal sleeve (4) which projects into a connecting part (5) and is held there in a ball socket ring (6) made of plastic.
  • the connecting part (5) corresponds essentially to the connecting part shown in DE-GM 93 0 ⁇ 6 761.5.
  • the actuating wire (3) runs out in an end part (7), at the end of which a ball socket element (8) is arranged, which is intended for attachment to a ball joint.
  • the end part (7) is starting from the connection part (5) over a certain Line surrounded by a guide tube (9), the connection part end of which is provided with a ball joint head (10 ⁇ ), which is also held in the ball socket ring (6), in such a way that deflections of 16 ° are possible.
  • a protective grommet (11) extends from the connecting part (5) and rests with its free end on the guide tube (9) and protects the interior of the connecting part (5) from contamination.
  • Another protective sleeve (12) at the end of the guide tube (9) serves the same purpose.
  • the connecting part (5) has a multiply stepped connecting sleeve (13) into which the ball socket ring (6) is embedded.
  • a cap (14) connected to the connecting sleeve (13) encloses the ball socket ring (6) and ensures that it is axially fixed within the connecting sleeve (13).
  • the connecting sleeve (13) has a receiving groove (15) in the area adjacent to the end part (7).
  • the receiving groove (15) is delimited in the axial direction on the one hand by a ring shoulder (16) and on the other hand by a ring web (17).
  • the ring web (17) and thus also the receiving groove (15) extend over approximately 270 °.
  • two locking webs (18, 19) project substantially radially outwards and in a V-shape, as can be seen in particular from FIG. (3).
  • the locking webs (18, 19) in the axial direction of the connecting sleeve (13) have a width that extends across the width of the receiving groove (15) and that of the ring web (17).
  • the ring shoulder (16) in the area outside the receiving groove (15) is withdrawn to such an extent that there is a distance between the latching webs (18, 19) and the ring shoulder (16).
  • FIG (4) a part of a holder (20 ⁇ ) for the connecting part (5) is shown. It is a sheet metal part that - which is not shown here - on one anywhere, for example on the body of a vehicle, can be attached.
  • the bracket (20 ⁇ ) has a thickness - perpendicular to the plane of the drawing - which is only slightly less than the width of the receiving groove (15) of the connecting sleeve (13).
  • the bracket (20 ⁇ ) has a U-shaped opening (21) which is delimited on both sides by U-legs (22, 23).
  • the radius of the lower part of the opening (21) corresponds essentially to the radius of the bottom of the receiving groove (15).
  • the U-legs (22, 23) run upward in obliquely outwardly directed end sections (24, 25) which are angled away from the perpendicular sections of the U-legs (22, 23).
  • the angle of the end sections (24, 25) to one another essentially corresponds to the V angle of the locking webs (18, 19) on the connecting sleeve (13).
  • the end sections (24, 25) have locking projections (26, 27) which protrude at right angles from the end sections (24, 25). From the latching projections (26, 27), in turn, sections extend obliquely outwards.
  • the connecting part (5) is inserted into the holder (20 ⁇ ) in that the connecting part (5) is inserted radially, ie laterally into the opening (21) in such a way that the edge of the opening (21) within the receiving groove (15) comes to rest, that is, on one side of the ring web (17) and on the other side of the ring shoulder (16). This goes so far without hindrance until the locking webs (18, 19) abut the upper edge of the holder (20 ⁇ ) in front of the locking projections (26, 27).
  • the latching webs (18, 19) must then spring slightly against one another in order to drive past the latching projections (26, 27). The effort required for this is dimensioned so that it can still be done by hand.
  • the locking webs (18, 19) spring back and come to rest against the obliquely extending end sections (24, 25).
  • the locking projections (26, 27) then prevent the connecting part (5) from moving out of the holder (20 ⁇ ) automatically.
  • the diameter of the bottom of the receiving groove (15), the radius of the lower part of the opening (21) and the arrangement of the locking projections (26, 27) are dimensioned such that the connecting part (5) has almost no play in the radial direction.
  • the course of the end sections (24, 25) and that of the locking webs (18, 19) are matched to one another in such a way that there is practically no play in the circumferential direction.
